Outline and evaluate the Psychodynamic approach to abnormality (12marks) It claims that personality develops in childhood through a number of ‘psychosexual stages’ and that too much or too little pleasure at one of these can lead to fixation and abnormal behaviour. For example between the ages of two and four children are in the anal stage – too much focus on holding in faeces during this time can lead to an ‘anally retentive’ adult personality which is obsessively neat and tidy‚ in some cases leading

Outline and evaluate the behavioural approach to abnormality This approach focuses on the behaviour of the person to explain psychological abnormalities. It believes that the behaviour is learnt‚ and therefore can be unlearnt. It focuses on 3 different things: classical conditioning‚ operant conditioning and social learning theory. Classical conditioning was developed by Pavlov through his work on animals. He explained the development of abnormal behaviours through stimulus-response associations

Outline and evaluate biological explanations of obesity Various explanations can be provided for the reasons of obesity‚ from biological explanations‚ to neurological and evolutionary theories. Even socio-economic reasons could give insight into why some people have a higher likeliness of obesity Evolutionarily‚ the thrifty gene hypothesis provides insight as to why many suffer from obesity‚ as it suggests that our current genes are no longer suited to our new environment. Modern day society is

Outline and evaluate biological explanations for aggression (24) The biological explanation for aggression states that aggression is innate behavior in people and the environment around them does not cause it. Neurotransmitters in the brain‚ chemicals that allow impulses to be transmitted from one area to another‚ can be used to explain why some people are aggressive. There is evidence to suggest that the neurotransmitters serotonin and dopamine are linked to aggression‚ low levels of serotonin

Outline and evaluate psychological explanations of schizophrenia (24 marks) Brown and Birley studied stressful life events in the role of relapse in schizophrenics. They found that 50% of people experience a stressful life event e.g. death‚ relationship break-up‚ job loss etc. in the 3 weeks prior to a schizophrenic episode.

Outline and evaluate the biological explanation of depression. Biological explanation of depression can be explained by neurotransmitter dysfunction. Neurotransmitters such as noradrenalin and serotonin have been shown to be linked with depression. Bunney at al (1965) found that there was low levels of noradrenaline function in the brain of depressed individuals. Also‚ post mortem studies found increased noradrenaline receptors in the brains of depressed suicide victims. When there is low noradrenaline
